Brief Summary

This study uses \[11C\]NPA positron emission tomography (PET) and a d-amphetamine challenge to image amphetamine induced dopamine release in the striatum in subjects with cocaine use disorders (CUD). Amphetamine-induced dopamine release data from this study will be correlated with \[11C\]NOP-1A VT measured at baseline in the midbrain. \[11C\]NOP-1A PET data will be used from aim 1 (see, Study Record: Imaging CRF X NOP interactions in Cocaine Use Disorders)
